+ * This has always just been a trie. Look at volume III of Knuth ACP

+ *
+ * ok, you start out with an array of pointers, each one corresponds
+ * to a letter at the current position in the command being examined.
+ *
+ * so roughly you have this for matching 'trie' or 'tie'
+ *
+ * 't' points -> [MessageTree *] 'r' -> [MessageTree *] -> 'i'
+ * -> [MessageTree *] -> [MessageTree *] -> 'e' and matches

+ * Obviously, there have to be more pointers
